SPARK-EX'.IIIIGUISHING'l APPARATUS.

appiication ined August 2s, 192s. serial No. 659,792. 1. Y

To all whom t may concern.'

Be it known that I, VICTOR DALLEMAGNE,

lcitizen of the French Republic, `residing atV f' boxes, and more generally toall chimneys,

either industrial or otherwise, with a View to stop thev sparks, regulate the draught, spare the iuel, and stop the soot, which device may be, if desired, located in a recess provided for the purpose.

Two embodiments of the invention are illustrated, by way of example, on the annexed drawing, in which:

Figure 1 shows an arrangement for locomotives, comprising a serpentine metal sheet combined with a conical steam battle cone;

Fig. 2 is a view oi an arrangement slightly modified as to certain details from that illustrated in Fig. 1 such modified arrangement being represented as` taken to pieces;

Fig. 3 is a view similar to Fig. 1, but showing a further modiiied` form of spiral balile;

Fig. 4 is a view generally similar to Fig. 2, but showing the modified form of spiral battle represented in Fig. 3.

The device shown in Figure 1 is essentially characterized by the combination of a spiral or serpentine metal sheet l, fast or movable, located in a drum 5 which encircles the exhaust pipe 2 and a baffle 3 which may take any shape, that of a cone, for instance.

Said baille, against which the sparks strike and go out as they escape from the lire, is located on an appropriate support linked to cylinder 4, itself located in the flue t of the locomotive, said cylinder being closed in its lower part by a truncated cone 9 which carries drum 5.

The object of baille 3 located above the serpentine metal sheet, is to reduce the section 01"' the steam passage and to direct the steam with a certain :torce against the walls of the tine, so as to increase the draught, especially when the lues are of a small height. The sparks issuing from the lire strike the serpentine metal sheet 1 and are extinguished.

The regulation of the draught is obtained by widening or narrowing, according to re-` quirement, the spirals of serpentine metalv sheet 1; by means of an appropriate device, consisting of two tightening parts 15, for instance.

In the form of execution shown in Figurev 2,1011 lthe ends of' serpentine metal sheet 1 are slidably ymounted two adjustable parts and 11` enabling the vserpentine metal sheet to vary in length, thus regulating the draught.

Said form of execution is further characterized in .that with a view to make, the` serpentine metal rsheet easily accessiblev when I it is required to remove it for cleaning or repairing the ytube system of the engine, the drum 5 is composed or threeelements a, b, c, which may be assembled by any appropriate means, such as hooks 6 engageable with kiepers 7. 'i

, 'Ihe upper edge of drum 5 is provided with an inturned rim or flange 8 having secured to it depending pins carrying rollers 9 which are designed to travel along an annular track or recess 10 formed 0n the lower edge of thel cone 9.

This latter arrangement is meant to keep up and guide elements a, b, c during their mounting and demounting. 4

In the form shown in Figure 3, the serpentine metal sheet 1 is replaced by a baille 1, here represented as of rusto-conical shape with its apex directed upward, said baiie being provided with a space or gap 9, the extent of which is controlled at will by means of the sliding parts 10 and 11.

Above the ap or open space .9 mentioned before, is placed a second battle 12 having, like the first one, sliding parts 13 to enable its surface to be varied at will. Said sliding parts may be controlled simultaneously with those of cone l.

Of course, the forms of execution hereinbefore described are given merely by way of example and the constructive dispositions may be vmodified without departing from the scope of the invention. y

Having now particularly described and ascertained the nature of my said invention as well as the manner inl which the same is to be performed, what I claim as new is:

1. A spark extinguisher, comprising a baflie adapted to be mounted on the exhaust pipe of a locomotive, a frusto-conical member located above the baffle and adapted to be attached to the stack of the locomotive, said member having an annular circumfericoV entialVV track at its lower endg' and an" open.l ended drum located below the frusto-conical member land enclosing the baHe, said drum having a continuous lateral iange or rim l at its upper end provided With roller-carrying members engaged vvith said/trackl to'su'spend the drum therefrom.

2. A spark extinguisher?, comprising a bale adapted to be mounted on the exhaust pipe of a locomotive,"a frusto-co'nical` member l'ocatedt above the battle and adapted to befattache'd to thefstacl of the locomotive,

said member having an annular circumfere'ntial trac-lr at'- its `lovv'e'rfe'nd,y :andi an openendeddrumy enclosing thebaile and having' a Vcontinuousflateral flange orrim at itsupper endprovided with roller-carrying members engaged vvithsai'd track to suspend4 the drum therefrom; said drum consisting oec.` a plurality-of similar sections havingcoactingfasteni'ng devices at'their kadjacent--edges' to removallfy connect them* together.

3. Tn a spark extinguisher, the'combina-4 tionl ofl a baffle adapted tobemounted on'the to vary its effective length; an open-ended drum enclosing the baffle; and supporting means for the drum. Y

4.V In al spark extinguisher, the combination of a baille adapted to be mounted on the eXhaust pipe of a locomotive; a pairof sliding plates adjustably mounted on the baffle to vary its etl'ectivel'en'gth; a truste-conical memberY adaptedA to be attached to the stack ofthe'locomotive above the baille; an openendeddrum'suspended fromy the lower end ofthe" frustfoiconical member and enclosing the'balile;y and a' baille With ther stack above and inline lwith the exhaust vpipe and the rstbale.

5; A spark eXtinguisher, `comprising' `a spiral metal sheet adapted' to be mounted on the exhaustv pipe of ya' locomotive, anda pair oty sliding plates' rvadjustably mounted on' the ends of said 'sheet to'vary its etfective'length.
